Abstract

A method of valuing resources of an asset intensive manufacturer. Calculations provide a MAV for each resource (machine) for each time horizon. The inputs for the calculations include the prices of products made by the resource, probalistic demand for the products, usage of the resource by various products, and availability of the resource. A series of equations, one equation associated with each resource, is formulated and solved, using lagrangian methods, with lagrangian multipliers representing resource values.
